While it was revealed yesterday that Apple executives Tim Cook and Eddy Cue had visited the company's new operations campus in Austin, Texas, Cook has just tweeted a photo of a second visit he made to Apple's nearby Mac Pro manufacturing facility.

Apple's Mac Pro manufacturing facility is run by Flextronics as part of an initiative to bring manufacturing of some Apple products back to the United States. While it is currently a limited effort given the relatively low volume of Mac Pro production, it has received considerable attention.

Flextronics' Mac Pro facility is roughly a mile from Apple's new Austin campus, which is actually an expansion of the company's long-standing operations campus in the city. The campus expansion is major effort that will see Apple investing $300 million to add at least 3,600 workers at the site by 2021. The overall project will encompass roughly one million square feet of space, with the just-opened first phase including two out of a planned six buildings on the site.

Following the visit to Apple's facilities in Austin yesterday, Cue was also spotted in the stands at last night's Game 1 of the NBA Finals just down the road in San Antonio.

Update 9:27 AM: Cook has also tweeted a photo of his (and Cue's) visit with the AppleCare team at the operations campus in Austin.

There's a light gray bar at the top, so I'm guessing VMWare Fusion or Parallels. When you're talking about electronic hardware and testing equipment, a lot of it only has Windows software so it's not like they have a choice.

Also, can anyone spot anything that might look like a Mac mini on that photo?

I was visiting Austin a few weeks ago and took a trip to The Alamo in San Antonio. And it wasn't a 3 hour drive! More like hour, hour and a half. Bumper to bumper traffic the whole way, then maybe 3 hours.

I think you'll find hardly any companies use OS X for manufacturing assembly lines. Practically all are Windows as the software written by third parties do not support OS X. Why would they?

You're post shows so much ignorance, Seriously. With that type of attitude things will remain the same. Is that what you want, to be monopolized by Microsoft? It's not like Macs are just a hobby. That's exactly what you're suggesting.
There's absolutely nothing about Windows in general that can only do that type of work. It's lazies that refused to create and consumers with your type of thinking that will keep everything the way it is. Very poor.
